I want to resize the product photos of my company. But when i resize the product to say some 500 width size and try to enlarge the image the image quality is not there. Can anybody let me know, how to resize the photo without affecting quality.
If the image is of something that can be easily be traced and you don't mind solid color/gradient on it then I suggest you vectorize it. You can use illustrator to vectorize and then it can be reshaped to any size and won't lose quality.
